Scuderi Group to Unveil Diesel Air-Hybrid Engine Design
The Scuderi Group announced today that they will be demonstrating the benefits of their breakthrough Air-Hybrid commercial diesel engine next week at the SAE Commercial Vehicle Engineering Congress and Exhibition which takes place Oct. 31 to Nov. 2 at the Donald E. Stephens Convention Center in Rosemont, Ill. (Booth 531)
The design and performance of the Scuderi Air-Hybrid Engine - potentially the world's most efficient internal combustion engine - has been verified by one of the world's leading independent engine testing laboratories. The Scuderi Air-Hybrid design is particularly well-suited for diesel systems.
With even a more dramatic impact on diesel engines than on gasoline engines, Scuderi technology improves the performance of diesel engines and reduces their complexity and cost.
"The innovations in the design of the Scuderi engine reduces the cost of diesel systems by eliminating or dramatically reducing three of the most expensive and complex parts of a diesel system - turbo charging, injectors and exhaust treatment," said Sal Scuderi, president of The Scuderi Group. "Because of the inherent design advantages of the Scuderi Air-Hybrid diesel engine, we estimate that this engine can lower the cost of diesel engines by as much as 40-50 percent. We strongly believe that the Scuderi Air-Hybrid engine is the diesel engine design of the future."
The Scuderi Air-Hybrid feature with the most significant impact on cost may well be the reduction or total elimination of the exhaust treatment system. Because the unique method of firing after top dead center is combined with a very fast moving power piston, the two biggest emission problems for diesel engines (NOx and soot) are eliminated or drastically reduced. With the sophistication and cost of the exhaust treatment systems growing rapidly, emission reduction has been the greatest challenge for today's diesel engine manufacturers. The newer urea-based Selective Catalytic Reduction (SCR) exhaust treatment systems can add from $11,000 to over $50,000 to the cost of large diesel engines. In addition, the extra weight and complexity increases the cost of maintenance and repairs.
Other Cost Savings
Because of the built-in supercharging capabilities of the Scuderi Engine, the need for turbochargers is also eliminated. The cost of turbochargers alone can save thousands of dollars per system.
Because the Scuderi Engine fires on half of its cylinders, only half of the fuel injectors are required. The cost of today's high pressure injectors can amount to over 30% of the base engine cost. In addition, because of the high turbulence created by the air transferring into the power cylinder from the transfer passage, the Scuderi Air-Hybrid Diesel Engine will be able to use low pressure, low cost injectors instead of expensive high-pressure injectors.
The Scuderi Engine
Developed by a team of fluid mechanic and thermodynamic experts, the Scuderi engine is expected to deliver a significant improvement in performance, efficiency and environmental impact. The Scuderi Group accomplished these advances by focusing on the fluid and thermodynamics at the heart of the engine, challenging conventional approaches to engine design in place for over 120 years.
As a result of this breakthrough design, and verified through the most sophisticated computer modeling available today, the Scuderi engine is expected to:
An Air-Hybrid Design
- Improve fuel efficiency in today's gas and diesel engines by almost one third
- Emit 80 percent less toxic emissions than today's gas and diesel engines
- Enhance the performance of hybrid engines
- Provide significantly more power than a conventional engine
- Be easy to manufacture because it utilizes the same components found in today's engines
By adding a small air storage tank with some simple controls costing only a few hundred dollars, the Scuderi engine can recapture energy normally lost during the braking of a vehicle. To accomplish this with electric hybrids requires a complex electrical system costing thousands of dollars, consisting of generators, motors, and large batteries. In addition, unlike electric hybrids, the Scuderi Air-Hybrid has the unique capability of recapturing energy from the exhaust of the engine, making it possible to utilize a Scuderi Air-Hybrid design in stationary applications such as electric generators - an application where electric hybrids are considered impractical.
Currently under development at a world renowned research and testing laboratory, the first diesel and gasoline prototypes are expected to be completed by late 2007.
